It's unclear how long the Barrel Roll trick has been up and running. Mashable reports the Easter egg is a tip of the hat to Star Fox 64, a scrolling shooter video game that debuted on the Nintendo 64 game console in 1997.

Here's another way to see the barrel roll: Type "Z or R twice" in Google Search. In the Nintendo game, Star Fox team member Peppy Hare instructs protagonist pilot Fox McCloud to "do a barrel roll," which the player achieves by pressing "Z" or "R" twice. The catchphrase has garnered Internet meme status.

"Do a Barrel Roll" is trending on Twitter, naturally.

"I want to do a barrel roll on every page on the Internet," wrote Twitter user Michael Litman.
